The invention relates to new 3-aryl-pyrrolidine-2,4-dione derivatives, to several processes for their preparation, and to their use as insecticides, acaricides and herbicides.

Pharmaceutical properties have previously been described of 3-acyl-pyrrolidine-2,4-diones (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenylpyrrolidine-2,4-diones were synthesized by R. Schmierer and H. Mildenberger Liebigs Ann. Chem. 1985 1095. A biological activity of these compounds has not been described.

Compounds of a similar structure (3-aryl-pyrrolidine-2,4-diones) are disclosed in EP-A 0,262,399, but a herbicidal, insecticidal or acaricidal action is not known in these cases.

Process (A) is characterized in that compounds of the formula (II) in which A, B, C, X, Y, Z, m, n and R³ have the abovementioned meanings are subjected to intramolecular condensation in the presence of bases.

Diluents which can be employed in process (A) according to the invention are all customary inert organic solvents. Hydrocarbons, such as toluene and xylene, furthermore ethers, such as dibutyl ether, tetrahydrofuran, dioxane, glycol dimethyl ether and diglycol dimethyl ether, and also polar solvents, such as dimethyl sulphoxide, sulpholane, dimethylformamide and N-methyl-pyrrolidone, can preferably be used.

Deprotonating agents which can be employed when carrying out process (A) according to the invention are all customary proton acceptors. The oxides, hydroxides and carbonates of alkali metals and alkaline earth metals, such as sodium hydroxide, potassium hydroxide, magnesium oxide, calcium oxide, sodium carbonate, potassium carbonate and calcium carbonate, which can also be employed in the presence of phase transfer catalysts, such as, for example, triethylbenzylammonium chloride, tetrabutylammonium bromide, Adogen 464 (methyltrialkyl (C₈ -C₁₀)ammonuum chloride) or TDA 1 (tris-(methoxyethoxylethyl)-amine), can preferably be used. Furthermore, amides and hydrides of alkali metals and alkaline earth metals, such as sodium amide, sodium hydride and calcium hydride, and additionally also alkali metal alkoxides, such as sodium methoxide, sodium methoxide and potassium tert.-butoxide, can also be employed.

When carying out process (A) according to the invention, the reaction temperatures can be varied within a substantial range. In general, the process is carried out at temperatures between 0° C. and 250° C., preferably between 50° C. and 150° C.

Process (A) according to the invention is generally carried out under atmospheric pressure.

When carrying out process (A) according to the invention, the reactants of the formulae (II) and the deprotonating bases are generally employed in approximately equimolar amounts. However, it is also possible to use one or the other components in a substantial excess (up to 3 moles).

Process (Ba) is characterized in that compounds of the formula (Ia) are reacted with carboxylic acid halides of the formula (III).

When the acid halides are used, the diluents which can be employed in process Ba) according to the invention are all solvents which are inert towards these compounds. Hydrocarbons, such as benzine, benzene, toluene, xylene and tetralin, furthermore halogenohydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride, chlorobenzene and o-dichlorobenzene, and additionally ketones, such as acetone and methyl isopropyl ketone, furthermore ethers, such as diethyl ether, tetrahydrofuran and dioxane, moreover carboxylic acid esters, such as ethyl acetate, and also strongly polar solvents, such as dimethyl sulphoxide and sulpholane, can preferably be used. If the stability of the acid halide towards hydrolysis permits, the reaction can also be carried out in the presence of water.

If the corresponding carboxylic acid halides are used, suitable acid-binding agents in the reaction of process (Ba) according to the invention are all customary acid acceptors. Tertiary amines, such as triethylamine, pyridine, diazabicyclooctane (DABCO), diazabicycloundecene (DBU), diazabicyclononbene (DBN), Hunig base and N,N-dimethyl-aniline, furthermore, alkaline earth metal oxides, such as magnesium oxide and calcium oxide, additionally alkali metal carbonates and alkaline earth metal carbonates, such as sodium carbonate, potassium carbonate and calcium carbonate, can preferably be used.

However, it is also possible to employ the carboxylic anhydride in a substantial excess (up to 5 moles). Working up is carried out by customary methods.

Process (Bb) is characterized in that compounds of the formula (Ia) are reacted with carboxylic acid anhydrides of the formula (IV).

If, in process (Bb) according to the invention, carboxylic anhydrides are used as the reactant of the formula (IV), the diluents which can preferably be used are those diluents which are also preferably suitable when acid halides are used. Besides, a carboxylic acid anhydride, employed in excess, can also simultaneously act as the diluent.

When carrying out process (Bb) according to the invention, the reaction temperatures can be varied within a substantial range, also when carboxylic anhydrides are used. In general, the process is carried out at temperatures between -20° C. and +150° C., preferably between 0° C. and 100° C.

When the process according to the invention is carried out, the starting substances of the formula (Ia) and the carboxylic anhydride of the formula (IV) are generally used in approximately equivalent amounts. However, it is also possible to employ the carboxylic anhydride in a substantial excess (up to 5 moles). Working up is carried out by customary methods.

Process (C) is characterized in that compounds of the formula (Ia) are reacted with chloroformic acid esters of the formula (V).

If the corresponding chloroformic acid esters are used, suitable acid-binding agents in the reaction in process (C) according to the invention are all customary acid acceptors. Tertiary amines, such as triethylamine, pyridine, DABCO, DBC, DBA, Hunig base and N,N-dimethylaniline, furthermore alkaline earth metal oxides, such as magnesium oxide and calcium oxide, and additionally alkali metal carbonates and alkaline earth metal carbonates, such as sodium carbonate, potassium carbonate and calcium carbonate, can preferably be used.

When the chloroformic acid esters are used, the diluents which can be employed in process (C) according to the invention are all solvents which are inert towards these compounds. Hydrocarbons, such as benzine, benzene, toluene, xylene and tetralin, furthermore halogenohydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride, chlorobenzene and o-dichlorobenzene, additionally ketones, such as acetone and methyl isopropyl ketone, furthermore ethers, such as diethyl ether, tetrahydrofuran and dioxane, moreover carboxylic acid esters, such as ethyl acetate, and also strongly polar solvents, such as dimethyl sulphoxide and sulpholane, can preferably be used.

When the chloroformic acid esters are used as carboxylic acid derivatives of the formula (V), the reaction temperatures can be varied within a substantial range when process C) is carried out. If the process is carried out in the presence of a diluent and of an acid-binding agent, the reaction temperatures are generally between -20° C. and +100° C., preferably between 0° C. and 50° C.

Process (C) according to the invention is generally carried out under atmospheric pressure.

When process (C) according to the invention is carried out, the starting substances of the formula (Ia) and the corresponding chloroformic acid ester of the formula (V) are generally used in approximately equivalent amounts. However, it is also possible to employ one or the other component in a substantial excess (up to 2 moles). Working up is then carried out by customary methods. In general, a procedure is followed in which the salts which have precipitated are removed and the reaction mixture which remains is concentrated by stripping off the diluent.

EXAMPLE 1 ##STR18##

3.9 g (0.13 mol) of sodium hydride (80% strength) are initially introduced into 70 ml of absolute toluene. After 36.2 g (0.107 mol) of N-2,6-dichlorophenylacetyl-N-isopropyl-glycine ethyl ester in 160 ml of absolute toluene have been added dropwise, the mixture is refluxed for 6 hours. 20 ml of ethanol are added dropwise while cooling in an ice bath, the batch is evaporated in vacuo on a rotary evaporator, the residue is dissolved in 1 N NaOH, and 3-(2,6-dichlorophenyl)-1-isopropyl-pyrrolidine-2,4-dione is precipitated at 0°-20° C. using concentrated hydrochloric acid. For purification, the product is boiled in chloroform, n-hexane is subsequently added, and the colorless product which has precipitated is filtered off with suction.

Yield: 25.42 g (83% of theory) m.p. >230° C.

EXAMPLE 2 ##STR19##

3.42 g (15 mmol) of 3-(2,4,6-trimethylphenyl)-1-methylpyrrolidine-2,4-dione are suspended in 50 ml of absolute tetrahydrofuran (THF), and 1.22 ml (15 mmol) of absolute pyridine and 2.54 ml (15 mmol) of ethyl-diisopropylamine are added. To this, 1.88 ml (15 mmol) of pivaloyl chloride dissolved in 5 ml of absolute THF are added dropwise at 0°-10° C., and stirring is continued for 30 minutes. The precipitate is filtered off, the solution is evaporated in vacuo on a rotary evaporator, and the residue is chromatographed on silica gel using cyclohexane/ethyl acetate 1:1.

Crystallization from ether/n-hexane gives 3.8 g (80.4% of theory) of 4-(pivaloyloxy)-3-(2,4,6-trimethylphenyl)-1-methyl-3-pyrrolidine-2-one of melting point 75° C.

Example 3 ##STR20##

5.18 g (20 mmol) of 3-(2,4,6-trimethyl-phenyl)-1-isopropylpyrrolidine-2,4-dione are suspended in 70 ml of tert.butylmethyl ether (MTB-ether). After addition of 1.63 ml (20 mmol) of absolute pyridine and 3.4 ml (20 mmol) of ethyl-diisopropylamine 2.45 g (20 mmol) chloroformic acid-iso-propylester dissolved in 5 ml of MTB-ether are added dropwise at 0° to 10° C. and stirring is continued for 30 minutes. The precipitate is filtered off, the solution is evaporated in vacuo on a rotary evaporator and the residue is chromatographed on silica gel using cyclohexane/ethylacetate 1:1. Crystallization from n-hexane gives 4.67 g (67.6% of theory) of 4-isopropoxy-carbonyloxy-3-(2,4,6-trimethylphenyl)-1-isopropyl-3-pyrrolin-2-one of melting point 81° C. The 3-aryl-pyrrolidine-2,4-dione derivatives of the formula (Ia)-(Ic), which are listed in Tables 1-3 below by way of their formulae, are obtained analogously to the Preparation Examples and following the general preparation instructions.

The active compounds according to the invention can furthermore be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

It is characteristic of the compounds according to the invention that they have a selective effect against monocotyledon weeds when used in the pre-and postemergence method, combined with a good tolerance by crop plants.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, and for the selective combating of weeds in annual cultures.

Here, the compounds according to the invention show a good tolerance by important crop plants, such as, for example, wheat, cotton, soy beans, citrus fruit and sugar beets, besides having an excellent action against harmful plants, and they can therefore be employed as selective weedkillers.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances and in coating compositions for seeds, furthermore in formulations using burning equipment such as fumigating cartridges, cans, coils, etc., and in ULV cold mist and warm mist formulations.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents, liquefied gases under pressure and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkyl-naphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloro-ethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water; liquefied gaseous extenders or carriers are those liquids which are gaseous at normal temperature and under atmospheric pressure, for example aerosol propellant, such as halogenohydrocarbons as well as butane, propane, nitrogen or carbon dioxide. As solid carriers there are suitable: for example ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumin hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dye-stuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilizing agents, acaricides, nematicides, herbicides or fungicides. The insecticides include, for example, phosphates, carbamates, carboxylates, chlorinated hydrocarbons, phenylureas and substances produced by microorganisms, inter alia.

The active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds, without it being necessary for the synergistic agent added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are employed in a customary manner appropriate for the use forms.

The active compounds which can be used according to the invention are also suitable for combating midges, ticks, etc.,in the sectors of animal keeping and cattle breeding; better results, for example higher milk production, greater weight, more attractive animal pelt, longer life, etc., can be achieved by combating the pests.

The application of the active compounds which can be used according to the invention occurs in this sector in a known fashion, such as by oral application in the form of, for example, tablets, capsules, potions, granules, by means of dermal or external application in the form of, for example, dipping, spraying, pouring-on, spotting-on and dusting, as well as by means of parenteral application in the form, for example, of injection, and, furthermore, by means of the feed-through process. In addition, application as molded articles (collar, ear tag) is also possible.

EXAMPLE A Nephotettix test

Solvent: 7 parts by weight of dimethyl formamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted to the desired concentration with water.

Rice seedlings (oryza sativa) are treated by being dipped into the preparation of active compound at the desired concentration, and larvae of the green rice leaf hopper (Nephotettix cincticeps) are placed on the seedlings while they are still wet.

After the desired time, destruction is determined in %. 100% denotes here that all the leaf hoppers have been destroyed; 0% denotes that none of the leaf hoppers have been destroyed.

In this test, for example the following compounds of the Preparation Examples show a superior activity compared with the prior art: (5), (54), (55), (56), (57), (58).
